Cbx750

[Bonez]

As some of you may know I'm buying a CBX750F. I've found a wealth of info on the interwebby thing, the links of the more interesting info I'll place in this thread. I'm interested in hearing about fellow KBers exploits with this bike and the CB700/750 Nighthawk range. Also interested to hear from those in the trade who've had to deal with them as well. Improvements, problems whatever.

I'll also use this thread as a resource for other info on the CBX750/CB700/CB750 Nighthawk range like I've done with my other bikes.

Awesome resource->http://www.teamrc17.net/

Also anyone got a workshop manual they can send me on CD or even a factory or Haynes/Clymer one in hard copy they have no use for?

Thanks.

Crikey, I didnt think your bulging garage could stretch to fit yet ANOTHER old jappa!!
You keep this up, Southwards will be after you to donate the collection some day:bleh:
Nice work.

[Bonez]

Thanks for the link MTRS. There's a Nighthawk manual but nothing CBX750 specific by th looks. The SC one I'll to get an idea of the hydraulic tappet setup. No dought that bloke down south I'll see this thread and post an auction for one on Trademe ;).

Storm this bike is a bit of a novelty for me-prolink suspention and suspention adjustments up the wazoo. So should provide a bit of entertainment. Getting rid of some of the kids furnature so room for another:doh:. Connies hinted about selling a few bibs n bobs but I've grown attached to my toys and I am fending her tooth n nail :argue:.

Early ones had crap crankshafts. (oil ports had very poor finish).
Watch out for dodgy valves/auto adjust lifters.
16" front wheel could be hell scary.
Powerful engine, until Suzi GSXR's stepped up to the plate.

[Bonez]

Downloaded the Brazilian parts book. Seems the CBX750 was manufactured/assembled there with cast wheels untill 1990.

[tri boy]

Images of Brazzilian babes in bikini's assembling m/cycles won't get out of my head...........both of them.:drool:
Thought the one i bought in 86 had an unusual new bike smell.................

[ynot slow]

Tyres try the Sport Demons,120/80-16 on my front and have on the rear 130/90-17 so you probably run similar.

[banditrider]

Time we saw a picture of your shed Bonez...

[slimjim]

yup i second that....

[Bonez]

Time we saw a picture of your shed Bonez...It's nothing special just has a half dozen or so battered/well used old jappers in it (not very "collectable" ones either with 3 having 100,000kms plus up)and some stuff I've collected for parts over the years.

Here's a pic of some of them from another thread-

Saw an immaculate GS1000 today at Ashhurst.

Mate I can vouch for the RC17 site. Viking runs a bloody good site there.
I used to be on the site alot when I had one.
They guys on the mailing list have such a depth of knowledge.
Rattly cam chains are an issue but Im sure you have that under control.
Have fun tinkering with your new toy.

[Bonez]

Picked the ol gal yesterday and did a wee pootle to see how she went.

Today popped her for a WoF checkup. Passed with flying colours so registered CuBix for 3months. Will sort out third party insurance tomorrow.

Also saw a mate to show it off. His exact words were-"You jammy cunt!!"

Went over it a bit more notice a few more cosmetic bits-n- bobs that will need to be sorted. Its had a heavy fall on the RHS (Mike mentioned a mate dropped it), the o'ring chain is a split link type with the clip on the inside with the OEM spockets still fitted. Noticed this while checking the rear shock and linkages. It has the longer dip stick and needs a top up. Will do an oil/filter change next payday. The consol that covers the instruments is missing a huge chunk of plastic on the LHS so it may have been down on that side as well at one point and the tripmeter is tits up at the moment but may be able to get the insty boys at work to sort that out.

Certainly nothing wrong with the wheel tracking though. Straight and true.

Hi If you join the teamrc17 group they send you a free workshop manual on CD.
I have a CBX750 in the garage & they sent me one.
Costs nothing to join just register your bike details with them.
If they don't look after you sent a PM to me and I can sort out a copy of my one. Cheers

Thank you very much.

No worries. If you check out their gallery of pics I posted up a few of rides in the South Island. My CBX went to Milford Sound and all over. Nice big tank so it was a great touring machine. Updated to a Firestorm but hung on to the CBX. Unfortunately it has some mechanical damage so it is off the road just at the moment.

[geoffc]

Just over 6 years I think. Memory not a strong point. I am registered on the
Teamrc17 site with the original purchase date and kms. They are hugely helpful and I chosen to still have their forum emails coming to me.

My old man had a CBX750 Bol when I was a teenager...I used to take it out on the sly when he was working sometimes....

[Bonez]

My old man had a CBX750 Bol when I was a teenager...I used to take it out on the sly when he was working sometimes....A stepson use to "borrow" my CB550 sometimes while I was at work. Thought I didn't realise it untill about 10 years later. We were chatting and I mentioned about the wheel marks in the grass ;).

Those Bol dor CBX750s are certainly good lookers. Someone made comment about CuBiX being out of character and a bit stylish for my tastes. I couldn't agree more.:cool: Hey, I guess there's aways hope......

[Bonez]

Bit of an update.

CuBiX doesn't like '91 low down-pinking a bit when under load. So will use '95 from now on. The headlights are brilliant, but will look into using a smaller running light for day time use. Rear damping adjustment cable seized but not a biggy at the moment as the set-up suits my style of riding, modest as it is, just fine- managed to move the damping too the intermediate setting carefully using a screw driver and rubber mallet, so the spring unit end is ok. Found out where the rear suspention air valve is. After giving it a decent blast over the last few rides (on a closed private road of course) a lot of oil seepage seams to have disappeared with a slight misting on the crank covers only. Pulled the air filter out and it looked like it hasn't been replaced or cleaned in the last 20 years. Bits of live stock, leaves and other crap encased in it. Looks better know but will is on the replace ASAP list. I'm surprised the bike goes so well considering it was breathing like an ashmatic.

Although the switch gear is the same as Gerble the different riding position certanly makes them easier to use. I've gotten use to the disco instrument setup. Still haven't reached reserve before having to fill up before yesterdays evening ride, with the fuel gauge below the red zone.

Am finding the Codura pants are sliding a bit on the seat, so the sheep skin will be used on those longer jornts in future. It's also interesting how much air the meager fairing deflects. I'm 6 ft and find it real comfortable. You kinda sit in the bike, in saying that it's quite an upright seating position.

Just been doing a bit more research and it turns out CuBiX is NZ new (for some reason I was under the impression it was an import), first registered in 1986. Meaning it's the full HP model (around 89-93 depending on what web page you look at) not a restricted Jap market model. Appears to have been dereged, then revinned in 1997.

Turns out 94-95 Honda Civic oil filters are suitable for the bike too, cool. That'll keep costs down.

Could have been left unregoed to need revine,at least you know the mileage should be true.

And to upset you the average age for Manawatu rides bikes has just entered a new bracket,sold the GSX and got Banditised into the 07 era,man the 20 yr difference is amazing re handling,brakes,lights.

Congrats in the new bike. CuBiXs headlights are better than some of the more exotic/newer bikes I rode with Friday night, it handles and brakes just fine given its performance. Still pulls like a school boy to 200kpm plus. Enough to loose my licence, one reason I bought the GB was to slow down.

I'm pretty keen on getting one of these bikes myself once I gather enough funds. Seems like a good idea as a commuter/long distance bike. Course I've already experienced the horrors of an old Honda so I'm not sure it's wise to expect it to be reliable. Would make a great project, but I've got enough of them...

Can anyone give me an excuse to get one besides "they look cool"?

Wonder if it's my old one.
Hitchehiked from Wanga's to Akld in early 86, to blue wing, Uncrated, and PDed it in their w/shop on a Sat morning, and rode it home that afternoon.
I pissed of to Oz in April/May 86, and it was sold via trade in at Eades H sometime in 86 while I was doing rude things to bacpacker lovelies in Cairns:buggerd::p:doobey::hug::drinknsin

Can anyone give me an excuse to get one besides "they look cool"?Smooth to ride, honk along at a reasonable clip if thats your thang, handle well around town, good fuel range, comfy, low mainenance(no tappet/shim adjustments every 5000 odd kms) and they're "old" so nobody wants them anymore ;).

The CB400 hornet type around 1994 ish imports are a nice sounding bike as well,saw one at Bulls,ideal smaller,but economical bike for a 250 rider/lady upgrading.The guy commented it is a great ladies bike(not in a derogitory way)but capable of sitting on 115km all day and top about 160km and some.And not heavy for ladies,great seat height.

Finally got around to doing an oil/filter change (44767 on the speedo). First bike with cartriged filter, so was a bit of a novelty. I bought a spring loaded filter remover some time back so Connie could open jar lids. She suffers from carpal tunnel so has little strength in her hands. It was a bit harsh on the old filter body so made up a strap filter remover out of an 8in length of 25 x 25 duragal box section and 10in length of 2in wide strop. Used some self tapping screws to hold the two ends ( over lapping a 1/2 in or so) to make a loop, Then slotted opposing corners of the box section with a cut of wheel on the grinder and slotted the loop in position. Done!. Does the trick nicely.

Just noticed I put a small dent in the filter body so have to be a bit more carefull next time-too ham fisted ;).

[Bonez]

After sorting out Gerbles speedo woes I decided to go for a spin on CuBix. Checking the tire pressures showed they where both 26 psi, around 6 -10 psi less than what they should be. Also fiddling with the front damper, TRAC and air settings. Still got to do a bit more triddling to do, but it certainly is a damn sight better than what it was. Starting to get the hang of her quirks.
Settled on clutchless up shifting. For me I need around another inch or so extra padding on the seat to get the bum to peg distance spot on. May even break into the piggy bank and get some gel grips.

For the moment I've settled on -

15 psi, 2 click on TRAC and position 1 on the damping up front.
40 psi, position 2 damping rear.
36 psi cold front and back tyres.

Subject to change.

I spied you riding out Main St-Pioneer Hwy around lunchtime,thought lucky bugger whilst I was working,then saw you return a while later.

[Bonez]

I spied you riding out Main St-Pioneer Hwy around lunchtime,thought lucky bugger whilst I was working,then saw you return a while later.Was hunting for bits for Gerble then. Buggers put a damn T intersection in while I wasn't looking. Got past Opiki and thought "this isn't right" I'm heading in the wrong direction should be heading towards the coast not the hills.

Bit amusing. Quite focused I was(typically unusal). Funny thing is though I already had the solution to the problem in the play pen ;). Good nice quiet solo blast the arvo though.

[Bonez]

After having a nice toodle yesterday I decided to get into sorting a few minor issues. Those being a leaking clutch cylinder and the lh oil line leak.

First the oil line. Simple to remove, drain the frame rail, undo one bolt and walla!
Hmmm shouldnt be two o'rings here. On closer inspection the inside one has a wee defect and it looks like someone thought it a good idea to slap another behind it. Easy fix. Yeah right.

Second the clutch slave cylinder. Been leaking since I got it. So disconnect the bango bolt, grab a plastic bag to slip the line into, nipple out, 3 bolts undone and out it come. Used the compressor to blow out the piston. On inspection of the seal there's hairline splits. The bore seems ok, bit of laquer build up. The seal the the push rod sits in was obviously affected by the brake fruid and needs replacing too. Polished up the piston. Hopefully it'll be ok with just new seals. Looking good so far though.

Popped in to City Honda to order to bits. Spoke to Mark, one of the mechanics, who put me on to the young falla at the parts counter. Finally got the parts required sorted, they'll be here tomorrow. Had to show the young fella where to look for my model on the online parts fiche.

Parts required:-

Clutch s/cyl
Cup seal p/n 22865-MBO-003
Oil seal p/n 91209-MBO-003

Oil line
O'ring p/n 91255-MJ1-000


Edit:- Got bits. Sorted the clutch slave cylinder. The piece on the oil line where the o'ring fit doesn't sit flush with the frame hense the two original two o'rings. One wont seal so in conjunction with that I've fitted a norrower one. Time will tell if this works.

[Bonez]

New rear tyre fitted- Shinko R110 130/80/18. $214 all up fitted. Will be interesting to see how it goes. Could'nt be any worse then the hardened BT45 it replaced. Hopefully it'll do 10,000kms without much effort. Paul from Manawatu M/C gave me a Conti tyre brochure to look at for referance and possible future tires. Will slap a new front on before the WOF is due next month. If anyone has any Suzuki GT750 bits lying about sing out, as he bought just bought one.

Oil line oil leak issue seems sorted. Bit of weeping here and there but nothing to cry about.
